PSU good enough?

So, I'm upgrading soon and can't decide on a PSU.
I found this PSU which is $50 atm because of a promo code.
So was wondering if it's enough for the parts I'm gonna order.
Link to the PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

CPU: Intel i5 3570K
MOBO: ASUS P8B75-V LGA 1155 Intel B75
GPU: Zotac GTX 660 2GB
RAM: G.SKILL 8GB
Optical CD/DVD player

Thanks
